VICKSBURG, Miss. - Louisiana State Police said cleanup of a chemical spill on the I-20 bridge connecting Louisiana and Mississippi is finished, and troopers are working to clear multiple 18-wheelers which crashed into each other early Wednesday morning.

At about 4 a.m., six 18-wheelers crashed after one slid into a railing on the icy bridge near Vicksburg, Miss. A tanker carrying a corrosive and flammable liquid material was rear-ended and leaked onto the bridge.

Louisiana State Police said the chemical, chloropropionic acid, also got into the river. According to troopers, chloropropionic acid is used in the agriculture and pharmaceutical industries.

DOTD routed eastbound traffic south onto U. S. 65 at Tullulah in order to cross the Mississippi River in Natchez. The leak also closed parts of the river Wednesday.

Troopers said they did not have an estimate for when the bridge could be reopened.
